They're great. I stood at the guitar shop after trying it out, thinking, "Will I ever actually use this? Probably not," and then bought it anyway. With the Magic off, they make for a good, weird, "broken" harmony pedal.

That's the only thing I use it for.
I'm selling mine, it's by far my least favorite Earthquaker pedal. I like gimmicky pedals, but it's just so much more fun to go modular if you're going to sound like that. Why have a canned box for that when you can get all kinds of variations by just fucking around?

Their Grand Orbiter might be my favorite phaser of all-time, though. Incredibly capable of a myriad of sounds.
